Several studies have reported a decrease in the reproductive capacity of the male due to heat stress and its effect on the production of reactive oxygen species (ROS) in sperm. Therefore, the objective of the present work is to show a general view of the risks of the warm environment, oxidative stress and the mechanisms by which there are an alteration in sperm capacity in the male. Sperm and seminal leukocytes produce most ROS. ROS cause damage to the sperm membrane (containing polyunsaturated fatty acids PUFAs), decreased motility, poor ability to fuse with the oocyte, and alteration of sperm DNA, causing poor embryonic development and low fertility. Therefore, the determination of ROS in sperm could be considered an alternative diagnostic tool to identify the etiology of male infertility.
